Experimental investigation of spark plug gap on performance and emission of single cylinder 4S SI engine with Hydroxygen as an additive

Abstract

The Hydroxygen as an additive to the gasoline is used in the present experimental investigation for reducing the fuel consumption and conserve the fast depleting fossil fuel without any engine modification. The Hydroxygen was produced from the developed electrolytic cell and the power of the alternator through the battery was used. The power to the electrolytic cell was controlled by circuit. During the experiment, the voltage and current across the electrolytic cell was measured by introducing the other circuit and data was collected. The experiment was conducted on Discover bike engine with constant Hydroxygen gas flow of 600 ml per hour to the engine intake manifold. Performance and exhaust gas emission parameters were measured by keeping 0.6 mm and 0.8 mm electrodes gap of spark plug (EGSP). Overall performance and emission was found to be optimum for 0.6 mm EGSP with Hydroxygen addition with the maximum relative decrease in brake specific fuel consumption 50.43%, increase in brake power and brake thermal efficiency (ƞ%) are 77.20% and 101.76% respectively, the maximum relative decrease in carbon monoxide, un burned hydrocarbon and nitrogen oxide are 96.96%, 90.29%, and 81.73% respectively.
